An oscillating multi-tool blade may comprise a blade body and a bonded material for cutting teeth harder than the blade body. A total depth of the bonded material may be greater than one and a half times a height of original blade teeth. The bonded material may comprise high-speed steel, tungsten carbide, or a material harder than the blade body. The blade body may be designed for resharpening or reshaping of the cutting teeth after the original teeth are dull, worn down, or broken. The blade may be initially created with no teeth, allowing a user to create custom blade teeth. The blade body may be designed for replaceable teeth, a strip of teeth, or replaceable material for shaping new teeth. The blade may be cryofrozen. The blade may have a secondary coating for added blade life or friction reduction.
